While the report is shocking I should commend Comic Relief, a aid organization set up by comedians in UK, which uses comedy and laughter to raise money and change lives. Check their website to learn about their great works.
It funds a lot of NGOs in Bangladesh to fight for those street children quoted in above report including Aparajeyo (Undefeated), Dhaka Ahsania Mission, CSKS etc.
Here is a thank you note from Comic relief to one of the donors:
...an enormous thank you to Willesden Short Story Prize for sending us the £5,000 donation to Sport Relief 2008. ... £15 could buy a set of books for 3 street children in Bangladesh for a year. With an education these young people will be better equipped to get a job when they are older and thus escape from the cycle of poverty they would otherwise be trapped in. ... It just goes to show, the money you donated really will change lives and we couldn't do it without your support so keep up the good work.
